password hash copy

Has this been changed in Ispconfig 3.0.4.6. When I copy and paste the hashcode from the password field in mysql to an identical server, it does not work. A few versions of Ispconfig before it has worked. I could easy copy the hashcode from the password field to another server. Is this a bug or a security thing

I go to phpmyadmin, and copy the hascode. Than paste it on the new server with the same e-mailaddress

As a test i did:

Under Ispconfig I filled in a password.
in phpmyadmin I copied the hashcode, and paste it in notepad.
Than I change the password in ispconfig for the same emailaddress.
In phpmyadmin I copied that hashcode, and paste it in notepad.
Than I copied and paste the first hashcode from notepad in the field under phpmyadmin.
So now the first password should be active again

This has worked in the past, but know it doesn't. Have I forgot some step(s).
